tech note:
Do I Need a Diaphragm Seal? Diaphragm Seals are designed for use with pressure gauges, switch- es or transmitters on process applica tions where: • The pressure measuring element materials capable of with standing corrosive effects of certain fl uids are not available. • The process fl uid being measured would normally clog the pressure measuring ele ment. • The process fl uid in the measuring ele ment might freeze due to changes in ambi ent temperatures.
